Brain Fitness Glossary

Giv­en the grow­ing aware­ness of this emerg­ing field, let’s review some of the most rel­e­vant con­cepts:

Brain Fit­ness: the gen­er­al state of good, sharp, brain and mind, espe­cial­ly as the result of men­tal and phys­i­cal exer­cise and prop­er nutri­tion.

Brain Fit­ness Pro­gram: struc­tured set of brain exer­cis­es, usu­al­ly com­put­er-based, designed to train spe­cif­ic brain areas and func­tions in tar­get­ed ways, and mea­sured by brain fit­ness assess­ments.

Chron­ic Stress: ongo­ing, long-term stress. Con­tin­ued phys­i­o­log­i­cal arousal where stres­sors block the for­ma­tion of new neu­rons and neg­a­tive­ly impact the immune system’s defens­es.

Cog­ni­tive train­ing (or Brain Train­ing): vari­ety of brain exer­cis­es designed to help work out spe­cif­ic “men­tal mus­cles”. The prin­ci­ple under­ly­ing cog­ni­tive train­ing is to help improve “core” abil­i­ties, such as atten­tion, mem­o­ry, prob­lem-solv­ing, which many peo­ple con­sid­er as fixed.

Cog­ni­tive Reserve (or Brain Reserve): the­o­ry that address­es the fact that indi­vid­u­als vary con­sid­er­ably in the sever­i­ty of cog­ni­tive aging and clin­i­cal demen­tia. Men­tal stim­u­la­tion, edu­ca­tion and occu­pa­tion­al lev­el are believed to be major active com­po­nents of build­ing a cog­ni­tive reserve that can help resist the attacks of men­tal dis­ease.

fMRI: func­tion­al mag­net­ic res­o­nance imag­ing (fMRI) is a non-inva­sive neu­roimag­ing tech­nique that enables researchers see images of chang­ing blood flow in the brain asso­ci­at­ed with neur­al activ­i­ty. This allows images to be gen­er­at­ed that reflect which struc­tures are acti­vat­ed (and how) dur­ing per­for­mance of dif­fer­ent tasks.

Heart Rate Vari­abil­i­ty (HRV): describes the fre­quen­cy of the car­diac cycle, and is one of the best pre­dic­tors of stress and anx­i­ety. Our hear rate is not “flat” or con­stant: HRV mea­sures the pat­tern of change.

Mind­ful­ness-Based Stress Reduc­tion (MBSR): yoga and med­i­ta­tion prac­tices designed to enable effec­tive respons­es to stress, pain, and ill­ness.

Neu­ro­ge­n­e­sis: the process by which neu­rons are cre­at­ed all through­out our lives.

Neu­roimag­ing: tech­niques that either direct­ly or indi­rect­ly image the struc­ture, func­tion, or phar­ma­col­o­gy of the brain. Recent tech­niques (such as fMRI) have enabled researchers to under­stand bet­ter the liv­ing human brain.

Neu­ro­plas­tic­i­ty: the brain’s abil­i­ty to reor­ga­nize itself by form­ing new con­nec­tions through­out life.

PubMed: very use­ful tool to search for pub­lished stud­ies. “PubMed is a ser­vice of the U.S. Nation­al Library of Med­i­cine that includes over 16 mil­lion cita­tions from MEDLINE and oth­er life sci­ence jour­nals for bio­med­ical arti­cles back to the 1950s. PubMed includes links to full text arti­cles and oth­er relat­ed resources.”

Work­ing mem­o­ry: the abil­i­ty to keep infor­ma­tion cur­rent for a short peri­od while using this infor­ma­tion. Work­ing mem­o­ry is used for con­trol­ling atten­tion, and deficits in work­ing mem­o­ry capac­i­ty lead to atten­tion prob­lems. Recent research has proven that work­ing mem­o­ry train­ing is pos­si­ble and help­ful for peo­ple with ADD/ ADHD.
